exactly the core of the cat also the narrow opening from the turbo to downpipe and the swan neck leading to the cat take a look at for example a miltek sports cat and downpipe 200 cell cat with 3" opening at turbo end which is a nice smooth flow into the cat rather than having the swan neck to restrict gas flow  :wink:

i just had the idea of using the cell from my oem unit inside my decat to build a DIY sports cat to save the swapping over mot time. if they were the same diameter that is..
